Product name: Polyethylenimine
CAS: 9002-98-6
Molecular Formula: C2H5N
Molecular Weight: 43.06
Product description:1, high adhesion, and adsorption of amino and carboxyl reaction can generate hydrogen. Amino and carboxyl reaction can generate ion. Generate covalence amino can react with carbonyl. Polyethylene imine with polar group (amino) and hydrophobic group (vinyl) structure, which can be combined with different material. Use of these general binding force, can be widely used in then, printing ink, coating, adhesive, etc. 2, high cationic polyethyleneimine exist in cationic polymerization in water, can all neutralization and adsorption of anionic substances, heavy metal ions can also pincers. With its high degree of cationic, can be applied to water treatment, paper making plating solution, dispersing agent. 3, reactive polyethylene imine because of the strong reactivity of primary amine and secondary amine, can easily with epoxy, acid, isocyanate compounds and acidic gas reaction. Using this feature can be used as reaction agent of epoxy resin, formaldehyde absorbents and dye fixative.
